This invention relates to apparatus for safe operation of jumper cables, and more particularly to a jumper cable assembly that provides light emitted from light emitting diodes (LED's) alongside the cable.
Jumper cables are employed to start a motor when the vehicle battery is too weak by connecting a more powerful battery with the weak battery. This may take place in the dark. Moving around in the dark between the two vehicles to connect their batteries, and then to enter the vehicle to start the motor while the cables are in place can be dangerous. If one trips over the cable, the connections may pull loose and cause sparking, burns, and fires.
U.S. Pat. No. 6,123,576 issued Sep. 26, 2000 to James discloses safety jumper cables that ensure correct connections, but do not address the problem of tripping over the cables in the dark.
U.S. Pat. No. 4,969,834 issued Nov. 13, 1990 to Johnson teaches two separate jumper cable segments with LED indicators of correct polarity connection that are first connected to each battery, and then to each other.
U.S. Pat. No. 3,942,859 issued Mar. 9, 1976 to Korodi teaches an extension cord with a male plug at one end and a female plug at the other end. A bulb energized by the cord illuminates a fiber optic in an elongate channel in the cord insulation to light up the cord along its length. In another embodiment, a neon gas in the channel is energized by the voltage in the cord to light up the cord.
U.S. Pat. No. 6,471,540 issued Oct. 29, 2002 to the applicant discloses a jumper cable assembly illuminated along its length by an electroluminescent element.
It would be useful to have a set of jumper cables that would be luminous along its length by light emitting diodes so that people would be less likely to trip over them in the dark that would also indicate correct polarity.
It is accordingly an object of the invention to provide a jumper cable assembly that has the usual connections at both ends for connecting two batteries in parallel. It is another object that the assembly emit light along its length when it is connected to at least one of the batteries for safety in avoiding tripping over the assembly. It is yet another object of the invention that the assembly automatically indicate when the proper polarity has been connected by use of inexpensive and trouble-free LED's that indicate polarity and provide light. The jumper cable assembly of the invention includes one or more LED's connected to the positive and negative wires, so that it will light up only when either battery is properly connected. A flexible, elongate fiber optic cable is illuminated by the one or more LED's and disposed alongside the positive and negative wires to thereby illuminate the cable assembly along its length. In another embodiment, a plurality of LED's may be disposed at intervals along the length of the cable to provide sufficient illumination of the cable to prevent someone from tripping over it. If the user connects first to the battery that is more easily seen, the light from the cable will help visualize the other battery. When the user has correctly connected a first battery as indicated by lighting the LED's, the negative terminal can be disconnected and the same procedure followed to connect the second battery correctly.
These and other objects, features, and advantages of the invention will become more apparent when the detailed description is studied in conjunction with the drawings in which like elements are designated by like reference characters in the various drawing figures.
